Modular Avionics Test Interface Boards

RS422 – LVDS – Discretes – TTL – Analog – FPGA Logic – SRAM

The McMOATI Boards (Digital & Analog McMOATI) are general purpose 3U cPCI test boards to used emulate a wide variety of payload or unique subsystem interfaces. Its intended use is for engineering and flight unit ground testing of critical space flight hardware. The board uses devices similar to those used on space flight hardware to ensure that functional and hardware compatibility are tested, even when actual subsystems are unavailable.

The McMOATI boards are a 3U cPCI compatible board designed as a general purpose test and interface boards. The designs provides a multitude of commonly found interfaces such as RS-422, LVDS, and digital and analog inputs and ouputs. In addition to these interfaces, the Digital McMOATI provides more than 1 GBytes of RAM and both have up to 8 MB of SRAM. At the heart of these resources is a 3M Gate fully reprogrammable XILINX Virtex-II FPGA with full access to all I/O, memory, and PCI bus.

With its large number and selection of resources, the McMOATI board can be used in many configurations. Example solutions based on the McMOATI range from a simple PCI based RS-422 interface board to a complete spacecraft subsystem hardware-in-the-loop testset, all implemented on a single or multiple McMOATI boards.

The McMOATI may be used as a standalone board with fixed logic or in more complex arrangements used along side other McMOATI and PCI boards in a cPCI system with a host CPU.

Broad Reach Engineering provides the McMOATI board in many configurations to best meet a particular need. Some applications may only require certain interfaces, in which case Broad Reach will ship an appropriately populated
board. Others may require an ‘out-of-the-box’ solution including a fully programmed FPGA and CPU based RTOS and test software.

Various versions of the McMOATI are in use at Broad Reach Engineering and customer locations for testing and simulation purposes. Let us put our testing and simulation experience to work in your project with this highly versatile and cost effective hardware & software solution.
